Description

Technical Field [0001] The present invention relates to an air conditioner and an air conditioner for a communication room,

[0001] The present invention relates to an air-conditioner-type air conditioner for a computer room communication apparatus and a cooling system having the same, and in particular, heat generated in communication equipment of an IT room is collected into a ceiling, (Cooling air circulation flow path) for cooling the communication equipment of the computer room and the flow path (waste heat discharge flow path) for forcibly discharging the computer room upper layer air are separately formed so as not to be mixed with each other, And more particularly, to an air conditioner and a cooling system including the air conditioner and the air conditioner.

Generally, communication equipment (for example, network equipment, servers, communication exchanges, etc.) is provided in a computer room such as a computer room of an enterprise, a bank, a school, a building, a laboratory, And the room temperature is always increased. If it is not cooled, there is a fear that the communication equipment may malfunction due to the overheating. Therefore, the room should be maintained at a proper temperature by using a separate air conditioner.

Therefore, most computer rooms are equipped with air conditioners such as air conditioners and thermostats and hygrostats, and the room temperature is properly maintained by appropriately cooling the room.

The communication equipment provided in the computer room may be, for example, a communication exchange, a server, or a network equipment.

However, in the conventional computer room (including both the communication room and the electronic exchange room), the heat generated by the communication equipment rises to the ceiling, and thus the heat that has risen to the ceiling forms a stagnated upper-layer air at the upper level.

The air in the upper layer of the computerized room served as a main cause of lowering the energy efficiency when the air conditioner was installed in the computer room, so that it was not possible to obtain a sufficient efficiency compared with the cooling load to be supplied.

Especially, in the case of the latest communication equipment recently introduced, the latest equipment of high efficiency continues to be introduced. Such a modern communication equipment collects a large number of functions into one (for example, However, since a large amount of load heat is generated, the high temperature air in the upper layer is generated more and more and the temperature is continuously increasing.

The air-conditioner integrated cooling system for a computer room communication apparatus according to an embodiment of the present invention includes an air-conditioner-integrated type air conditioner 100 for a communication device, a ceiling inlet 211, and an inlet duct 210 .

The air conditioner-supply / air-conditioning type air conditioner 100 for communication equipment has the structure described above based on Figs. 1, 3, 4 and 5.

In the air-conditioning integrated type air-conditioning system for a computer room communication apparatus according to an embodiment of the present invention, in order to exhaust the upper-layer air exhausted through the upper-layer air outlet 138 and connected to the upper- And an exhaust duct 220 is further included.

Hereinafter, the operation of the air conditioner-integrated air conditioner 100 for communication equipment according to an embodiment of the present invention and the air conditioner-integrated cooling system for a computer room communication apparatus having the same will be described.

First, the operation of cooling the computer room in the summer or the spring and autumn season by the operation of the cooling cycle and discharging the waste heat by the air in the upper layer of the computer room to the outside will be described.

The control unit receives temperature values from the room temperature sensor 161, the outside temperature sensor 162 and the upper temperature sensor 163 and sets the set room temperature Trs in the internal memory (not shown) The outside temperature (Tos) and the set upper temperature are stored in the internal memory.

When the current room temperature Trp received from the temperature sensor is equal to or higher than the set room temperature Trs (for example, 20 ° C to 25 ° C) and the current outside temperature Top is equal to the set outside temperature Tos (for example, The control unit 160 skips all the temperature values received from the upper temperature sensor 163 in the case of the cooling mode (cooling cycle operation mode) in which cool air is generated by the operation of the cooling cycle Since the condenser fan 134 always operates, the waste heat in the upper portion is always forcedly sucked and discharged regardless of the temperature of the upper portion.

When the current room temperature Trp is equal to or higher than the set room temperature Trs (for example, 20 ° C to 25 ° C) and the current outside temperature Top is equal to or higher than the set outside temperature Tos (for example, 10 ° C to 15 ° C) , The control unit 160 outputs a drive control signal to the compressor driving unit 120 to drive the compressor 121 and forcibly sucks the high temperature air in the upper portion of the computer room R to cool the air cooled condenser 122 At the same time, the condenser fan driving unit 133 outputs a condenser fan driving control signal to the condenser fan driving unit 133 for driving the condenser fan 134 in order to exhaust the hot air in the upper layer, and outputs a cooling fan driving control signal for driving the cooling fan 132 And outputs an outdoor damper off drive control signal for closing the outdoor air damper 152 to the outdoor air damper driving unit 151 and outputs an indoor damper on drive control signal for opening the indoor damper 154 to the cooling fan driving unit 131 And outputs it to the indoor damper driving unit 153 .

According to the control operation of the control unit 160 as described above, the cooling air discharge operation is performed while the cooling cycle is being performed, the cool air discharge opening 115, the lower layer of the computer room R, the cooling of the communication equipment, the middle layer of the computer room, A cool air circulation passage (dotted arrow mark) consisting of an air inlet 111 -> an evaporator 123 -> a cooling fan 132 is formed.

The heat generated in the communication equipment 10 of the computer room R is collected in the ceiling C1 and the high temperature upper air of the ceiling C1 thus collected passes through the ceiling inlet 211, the inlet duct 210, The air intake port 136 to the upper space S1 and the air-cooled condenser 122 to condense the condenser 122 to the condenser fan 134 to the upper air outlet 138, 220) (solid line arrow).

The cool air circulation flow path is a flow path extending from the lower part to the central part and not a flow path coming out from or entering the upper part, and the waste heat discharge flow path is formed only in the upper part So that the cool air circulation flow path and the waste heat discharge flow path are separated without being mixed with each other.

(For example, 25 to 30 DEG C or more) of the upper layer can be discharged in a state in which the high temperature waste heat in the upper layer is not mixed with the cold circulation flow path, and as a result, the energy efficiency of the cooling system 100 is improved.

Layered air having a middle temperature (for example, 18 to 25 ° C) of the intermediate layer of the computer room R, heat exchange efficiency can be improved compared to heat exchange with high temperature heat.

As described above, the air-cooled condenser 122 is provided on the flow path for discharging the hot air at the upper portion of the upper stage, so that the air-cooled condenser 122 can be operated in the process of exhausting the upper- Cooling (the high-temperature air in the upper portion is used as the condensation heat of the condenser).

The upper layer air forced through the upper air intake port 136 is about 25 to 30 degrees Celsius (does not exceed 35 degrees Celsius), and the condensation temperature of the condenser is 35 to 40 degrees Celsius, (The condenser 122 can condense to the air at a temperature of 45 degrees Celsius).

The air-cooled condenser 122 can be installed in the housing 110 without being disposed outdoors because the condenser 122 can be cooled using the high-temperature upper air in the ceiling of the computer room.

Since the condenser 122 can be provided inside the housing as described above, the piping distance to the compressor 121 is extremely shortened, thereby increasing the efficiency of the cooling cycle. In the case of the conventional condenser, It is possible to reduce the initial installation cost of the conventional condenser.

Since the waste heat in the upper portion is forcibly sucked and discharged by using the condenser fan 134, which is the oldest, it is not necessary to provide a separate exhaust facility.

Next, the operation in the case where the computer room R is to be cooled using the outside air having a low temperature in the case where the outside air temperature is low as in the winter will be described.

Since the operation of the condenser fan 134 is stopped in this case, the temperature value received from the upper-stage temperature sensor 163 is received as the current room temperature Trp is equal to or higher than the set room temperature Trs (for example, 20 ° C to 25 ° C) If the current outside temperature (Top) is below the set outside temperature (Tos) (for example, 10 ° C to 15 ° C) and the current upper temperature is above the set upper temperature (25 to 30 ° C) The controller 121 outputs a driving stop control signal to the compressor driving unit 120 to stop the operation of the compressor 121 and forcibly sucks the hot air at the upper portion of the computer room R, A condenser fan drive control signal for driving the condenser fan 134 to exhaust the high temperature air of the cooling fan 132 to the condenser fan drive unit 133 and outputs a cooling fan drive control signal for driving the cooling fan 132 to the cooling fan 132. [ The drive unit 131 And outputs an outside damper on driving control signal for opening the outside air damper 152 to the outside air damper driving unit 151 and an inside damper off driving control signal for partially closing the inside damper 154, (153).

In this cooling mode, although the operation of the cooling cycle is stopped, since the outdoor air is cooled by the cold air, the outdoor air of low temperature introduced into the outdoor air inlet 113 flows from the cooling fan 132 to the cold air outlet 115 to the computer room R A cooling air circulation flow path consisting of a lower layer of the communication equipment, cooling of the communication equipment, middle layer of the computer room, cooling of the communication equipment, indoor air inlet 111, and evaporator 123 is formed.

The heat generated in the communication equipment 10 of the computer room R is collected in the ceiling C1 and the high temperature upper air of the ceiling C1 thus collected passes through the ceiling inlet 211, the inlet duct 210, An air intake port 136, an upper space S1, a condenser fan 134, an upper air exhaust port 138, and an exhaust duct 220.

Finally, the operation in the case where it is not necessary to cool the computer room but the temperature of the upper layer portion is high and needs to be exhausted will be described.

If the current room temperature Trp is less than the set room temperature Trs (for example 20 to 25 degrees Celsius) and the current upper temperature is higher than the set upper temperature (25 to 30 degrees Celsius), the controller 160 controls the compressor 121 To the compressor driving unit 120 and outputs a driving stop control signal for stopping the driving of the cooling fan 132 to the cooling fan driving unit 131, R to the condenser fan driving unit 133 to drive the condenser fan 134 to exhaust the hot air at the upper portion of the condenser fan driving unit 133. [

In this case, since there is no introduction of outside air and there is no operation of the cooling cycle, the cool air circulation channel is not formed, but the communication equipment 10 of the computer room R continuously generates heat, And the high temperature upper air of the ceiling C1 which is gathered in this way passes through the ceiling inlet 211, the inflow duct 210, the upper air intake port 136, the upper space S1, the condenser fan 134, > An upper air exhaust port 138, and an exhaust duct 220.
